Aircraft synthetic vision system for approach and landing
First Claim
1. An aircraft synthetic vision system for approach and landing, comprising:
- a runway assistance landing system;
a plurality of databases containing data;
a first apparatus determining augmented coordinates;
a second apparatus detecting the likelihood of an error in determining the altitude from at least one of the runway assistance landing system, the plurality of databases, and the first apparatus, and identifying the error;
a processor capable of generating symbology commands defining a runway environment in response to data provided to the processor from each of the runway assistance landing system, the plurality of databases, and the first and second apparatus; and
a first display coupled to the processor for displaying the runway environment and aircraft approach status.

Abstract
An aircraft synthetic vision system (100) is provided for increasing data input to a pilot (109) during approach and landing flight operations, and includes a runway assistance landing system (114) and a plurality of databases (106, 108, 110, 112) which may include, for example, a terrain database (106), an obstacle database (112); and a validated runway database (110). The processor (104) detects the likelihood of an error in determining the altitude from at least one of the runway assistance landing system (114), the plurality of databases (106, 108, 110, 112), and identifies the error. The processor (104) further determines augmented coordinates, and a processor (104) generates symbology commands to a first display (116) for displaying a runway environment in response to data provided to the processor (104) from each of the runway assistance landing system (114), the plurality of databases (106, 108, 110, 112), and the processor (104).
